[Aortic insufficiency secondary to an unruptured congenital aneurysm of the sinus of Valsalva].

Congenital aneurysm of the sinus of Valsalva is an uncommon entity. Its diagnosis is rare in infancy because most cases are asymptomatic. This condition is usually detected in adults as incidental finding or a complication due to aneurysm. We report a five-year-old asymptomatic child, with a congenital unruptured aneurysm of the right sinus of Valsalva. It was diagnosed on two-dimensional and Doppler echocardiography, and confirmed by angiography showing an aortic regurgitation. The aim of this publications is to report another case of this rare condition in pediatric cardiology, which real importance is probably subestimated because of unusual clinical manifestation. Nevertheless, the increasing use of the two-dimensional and Doppler echocardiography will provide much more cases of this entity. Diagnosis and treatment are reviewed as well as bibliography.
